Background information:
On construction sites we find construction cabins. They are available in many different versions. Some accommodate toilet groups or lunch areas, where construction meetings often take place. The foreman usually also has his own office in a construction cabin. And on some construction sites, such a cabin is also used to store the more expensive, but daily necessary tools. This means that the larger construction sites sometimes have 6 or more construction cabins and that takes up valuable space. Construction sites, especially in the city, are small in size and often a large building has to be erected on that small space. This caused builders to stack the construction cabins. The cabins on the first floor are then reached by an external staircase and are often interconnected. One, or sometimes two, stairs are therefore sufficient to reach the entire top row of construction cabins.
Architectural details:
The stairs are usually made of galvanized steel. So that they can withstand the various weather influences. Certainly in the early days of this construction cabin "stacking method", various stairs were used. Basically just what the construction company had in stock. But what often happened from the start is that a staircase was placed parallel along the long side of the construction cabin, with a platform at the top in front of the door. Later on, occupational health and safety rules were also introduced for these stairs, which often meant that the steeper stair models and also those with a low handrail had to be taken out of circulation.
